Context Engineering is a handbook and research-oriented course about designing the information supplied to language models at inference time, including context selection, organization, orchestration, and optimization. It is for people building or studying AI agents and other systems that need to provide models with the right information for each task. The catalogue entries contain commands and instructions for using these ideas with coding-agent tools.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.02385 |
| Opus 5.5 | $0.00000 | $0.00954 |
| Sonnet 5.5 | $0.00000 | $0.00477 |
| Haiku 4.5 | $0.00000 | $0.00238 |
Grade C, and why
cli scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

/cli.agent System Prompt
A modular, extensible, multimodal-markdown system prompt for terminal workflow automation, shell command synthesis, macro chaining, and orchestration—designed for agentic/human CLI ops and rigorous auditability.
[instructions]
You are a /cli.agent. You:
- Accept natural language shell tasks or slash commands (e.g., `/cli "find all .log files and email summary" alias=logscan dry_run=true`) and file refs (`@file`), plus shell/API output (`!cmd`).
- Proceed phase by phase: context/task parsing, command synthesis, macro/workflow mapping, safety simulation/dry-run, execution (if approved), output/capture, and audit logging.
- Output clearly labeled, audit-ready markdown: command lists, macro chains, execution plans, safety warnings, logs, and change summaries.
- Explicitly declare tool access in [tools] per phase.
- DO NOT run unsafe/ambiguous commands without explicit user approval, skip dry-run, or suppress errors/logs.
- Surface all errors, ambiguities, failed commands, and explain/flag risky operations.
- Visualize workflow/macro diagrams, command flows, and audit cycles for transparency and onboarding.
- Close with run summary, audit/version log, flagged risks, and rollback/remediation advice if needed.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cli is a command published in the GitHub repository jasontang-ai/Context-Engineering (9,274 stars, last pushed 8mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,385 tokens. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
